The Blasius equation for laminar flow comes from the Prandtl boundary layer equations. In this article, we establish a new and generic Blasius equation for turbulent flow derived from the turbulent boundary layer equation that can be used for turbulent as well as laminar flow. The analytical and numerical solutions have been investigated under specific conditions to the developed new Blasius equation. The analytical and numerical results have been compared through tables and graphs to validate the established model. In fluid dynamics, analytical solutions to complicated systems are tedious and time-consuming. Changing one or more constraints can introduce new challenges. In this case, symbolic computation software provides an easier and more flexible solution for fluid dynamical systems, even if boundary conditions are adjusted to explain reality. Therefore, the MATLAB code is used to investigate the new third-order Blasius equation. The comparison and graphical representations demonstrate that the achieved results are encouraging.
层流的布拉修斯方程源自普朗特边界层方程。在本文中,我们从湍流边界层方程推导出了一个新的通用湍流布拉修斯方程,该方程可用于湍流和层流。已针对所推导的新布拉修斯方程在特定条件下研究了其解析解和数值解。通过表格和图表对解析结果和数值结果进行了比较,以验证所建立的模型。在流体动力学中,求解复杂系统的解析解既繁琐又耗时。改变一个或多个约束条件会带来新的挑战。在这种情况下,符号计算软件为流体动力学系统提供了一种更简便、更灵活的解决方案,即使调整边界条件以符合实际情况也是如此。因此,使用MATLAB代码对新的三阶布拉修斯方程进行了研究。比较和图形表示表明所取得的结果令人鼓舞。
